I think I would want to install the new cpu-it's the same model as the old one; intel i5 760. The used cpu is Intel 540 i3. That's the only legitimate reason I can imagine. Anyway, a wreath of gratitude to everyone for their wonderful support.

Your welcome.

You did the right thing with testing of the used ebay CPU, so I suggest you follow the same steps for the new on.

After you are able to Boot into the BIOS ( with the OS HDD not connected) > load Default setting, > restart, enter the BIOS again, > Check, language/time/date, > Check that storage is set to AHCI, > check the RAM is set to XMP, (if available) > Save setting, exit. After the restart, > shut down, > connect the OS HDD, test.

Just looked at your manual and, yes, F2 will load defautl settings. You will still need to enter the BIOS to check the settings I mentioned as on some boards, Default for storage controller is set to IDE, and RAM will not have the XMP profile enabled.

Weird stuff here. Computer is breadboard status and works normally. But after installing it back into its full size tower, it won't turn on. Checked all the connections and cleared cmos several times. My computer is possessed or something.

Sorry to hear you are still having problems.

Temps. I think that some CPUs just run hotter than others, 39C is warm but 30ish at idle would be better. I am in the middle of testing a new build, i7 4790K, stock cooler custom TIM, everything else installed, running idle in a full tower, side still removed, 39C. Not terrible happy, hope it comes better once closed up.

Do the PSU and CPU fans spin up?

I suggest you work backwards to try and find the issue. Testing between every step.

Disconnect all fans except the CPU, then,

Front USB 3.0.

Front USB, 2.0.

Front sound.

Case panel controls.

Optical drive.

HDD.

Monitor.

GPU.

RAM.

If still won't boot. Possible the board is cracked, or a broken trace, or (highly unlikely) a screw is shoring out at the MB screw hole.

Remove the top row of MB screws.

Then the bottom row.

Then first two screws closest to the back panel ports, leaving one, middle/right side.

If still fail, put one screw, middle row, closest to the back panel ports, remove the right side middle one.
